Height of Tide

« Back to Glossary Index

The vertical distance at any instant between sea level and chart datum

The height of tide refers to the vertical distance between the water level at a specific point on the shore or in a body of water and the reference level, usually the chart datum or the mean sea level. It is a crucial measurement for navigation and maritime activities as it determines the depth of water available for vessels to navigate safely. The height of tide varies throughout the day due to the gravitational forces of the moon and the sun, as well as other factors such as wind and atmospheric pressure.
